"Unsafe" means that when you break the contract of `unsafe-fl/` by providing a fixnum second argument, then anything can happen. The result might be to crash the Racket process, or it might be the result that `/` would have produced. Unfortunately, you can't draw any conclusions from the result of breaking an unsafe operation's contract. ____________________ Racket Users list: http://lists.racket-lang.org/users
